Specification of"heiter"s` liaitent.

Patented June 24, 1919.

Application filed August 21, 1918, Serial No. 250,835.

To all whom t may concern:

Be it known that I, ALFRED TAGGART, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Plasterers Darbies; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in a darby for plasterers use and it has for its object a simple and eiiicient device of this character cheaply constructed, which is made of separable parts for convenience in packing and storing.

I am aware ofthe fact that darbies constructed of sheet metal adapted to be tele-` scoped within a small compass have been heretofore constructed. I have found, however, that the best results are not obtained by the use of a metal surface, and one of the essential objects of my invention is the provision of a darby, the body portion of which is constructed of wood, the sections being separable and adapted to be confined within a small compass. j

My invention consists of further various details of construction, combination and arrangement of parts which will be hereinafter fully described, shown in the accompanying drawings and then speciically defined in the appended claim.

My invention is illustrated in the accompanying drawings which, with the letters of reference marked thereon, form a part of this application and in which:

Figure 1 is a plan view of a darby constructed in accordance with my invention,

the parts being shown as united and the' device in readiness for use.

Fig. 2 is an edge view of same.

Fig. 3 is a sectional view on line 3-3 of Fi'. l.

Fig. 4 is a sectional view on line 4 4 of Fig. 1, and

Fig. 5 is a large detail showing the joint used in connecting the parts.

`Reference now being had tothe details `of the drawings by numerals:

1 and 2 represent the sections of the body portion of the darby, the sections being of equal length, the inner ends of which have portions reduced in size as at 3, and which, when the device is prepared for use, are fitted within the metallic sleeve 4, the outer which they are connected.

`The sections 1 and 2 have recesses 3', 3 1n their adjacent ends which latter telescope within a sleeve 4 apertured as at 4'. When the sections are end to end, a screw G is passedthrough the apertures 4 and said recesses 3', and theend of the screw engages a -nut 8 (see Fig. 3) seated in a countersunk recess 7 in the strip 5. Other screws similar to the screw 9 are formed through the sections 1 and 2 and strip 5 and engage nuts 6 seated in a countersunk recess 7 in the strip- 5. i

l0 designates the handle which serves as a pivotal pointl in the use of the tool. Upon referring to Fig. 4 of the drawings, it will be noted that the rear face of section 1 is provided with an interiorly screw threaded chamber l1 within which is seated the screw threaded base 12 of the member 13, which member is provided with an upward extension 14 which is seated within the opening provided for its reception in the ,longitudinal center of the handle, the free end of said extension 14 being rectangular in cross section and has its free end beveled to permit of its being driven into the handle.

The lower end of the screw threaded base 12 is provided at its center with an extension 17 formed and serving as a screw driver suitable for use in setting the screws 6-6 and for other purposes for which the same might` be used. In order to protect the end of the darby, which when in operation is liable to injury from the mortar board, a metallic band 20 is provided.

That I claim to be new is:

A darby, comprising two sections, the adjacent ends of which are reduced in size, a

shell Within which said reduced portions In testimony whereof I hereunto aix my telescope7 a lookin@ block fastened to said signature in presence of two Witnesses.
